Weight-length, length-length relationships and form factor of three flatfish species from the Bay of Bengal, Bangladesh

Biometrics such as weight-length relationships (WLRs), length-length relationships (LLRs), as well as form factor (a3.0) were investigated for three flatfish species, Cynoglossus lingua, Cynoglossus arel, and Brachirus pan which were captured using seines and gill nets between September 2021 and March 2022 from the Bay of Bengal, Bangladesh. The lengths were measured to adjacent 0.1 cm accuracy with a digital caliper and weights to the accuracy of 0.01 g with a digital balance for each individual. The WLRs were accurately adjusted for all species (r2 > 0.9500). Brachirus pan had the lowest b value of 2.9543, whereas C. arel had the highest b value of 3.2924 amongst the three species. For the investigated species of fish, LLRs were also highly significant (r2 > 0.9600, p < 0.01). The estimated form factor values were 0.0023 for B. pan, 0.0026 for C. arel, 0.0027 for C. lingua. New maximum total lengths for C. arel and B. pan have also been recorded. Since there are no weight-length relationships (WLRs), length-length relationships (LLRs), as well as form factor (a3.0) data for these species in Bangladesh; the information supplied here expands the depth of knowledge for these species

Formulation and substantiation of homemade complementary baby food by selective feeding trial

The complementary food was prepared from dried grinded corn, bengal gram and sesame seed, banana, pumpkin and sugar with adequate amount. The results indicated that the crude protein, lipid, fibre, ash, moisture, energy and carbohydrate were higher than values in the proprietary formula. To evaluate the efficacy of this low cost complementary baby food on the growth of children between the age group 1 to 2 years and intervention program was carried out in an urban slum. For this trial feeding 18 children with various degrees of malnutrition were selected from slum dwellers by anthropometric indices. The children were classified as control and feeding group. The anthropometric indices of these children showed that control group suffers from continuous weight loss where as the feeding group showed positive correlation with the growth curve. Thus, complementary food processed from locally available food commodities must have a great potential in providing nutritious foods

Quality of Service in Software Defined Networking

Software Defined Networking SDN promises to provide a powerful way to introduce Quality of Service QoS concepts in today s communication networks SDN programmatically modifies the functionality and behavior of network devices using single high level program Software Defined Networking SDN instantiation OpenFlow has been designed according to these properties The realization of Quality of Service QoS concepts becomes possible in a flexible and dynamic manner with SDN This paper focuses on the existing architectures parameter such as response time switch capacity and bandwidth isolation that is calculated here Although concepts of QoS are well researched they were not realized in communication networks due to high implementation complexity and realization costs OpenFlow as the best-known SDN standard so far defines a standard protocol for network control These observations of switch variety may provide SDN application developer s insights when realizing QoS concepts in an SDN-based networ

Marketing System of Shrimp in Some Selected Areas of Bangladesh

A study was undertaken to examine the marketing system value chin analysis of shrimp in selected areas of Khulna district of Bangladesh during the month of March-April 2012. The objectives of the study were to estimate costs and margins, seasonal price variation and to test market integration of shrimp. Primary were used for this study. The higher marketing cost was incurred by aratdars and the lowest by retailer. On the other hand, retailers earned the highest net marketing margins.T he findings of the study revealed that the marketing of shrimp was a profitable business and some recommendations were provided for the improvement of shrimp marketing in the country.

Analysis of Marketing Efficiency, Value Addition and Spatial Co-Integration of Mozambique Tilapia (Oreochromis mossambicus) Fish in Some Selected Areas of Bangladesh

A study was undertaken to examine the value chain, value addition, marketing cost & margin, marketing efficiency and market integration of tilapia fish in selected areas of Bangladesh during the month of June-July 2013. The objectives of the study were to estimate costs and margins and to test market integration of tilapia fish. Primary and secondary data were used for this study. The higher marketing cost was incurred by paiker and the lowest by retailer. On the other hand, retailers earned the highest net marketing margins. Chain II was found the most efficient chain. Analysis of market integration shows that tilapia fish market in Bangladesh was well integrated. The findings of the study revealed that the marketing of tilapia was a profitable business and some recommendations were provided for the improvement of tilapia marketing in the country. Keywords: Value addition, marketing cost & margin, marketing efficiency and spatial co-integratio

UGROŽENE VRSTE RIBA U SVIJETU: Mystus gulio (Hamilton, 1822) (Siluriformes: Bagridae)

Long whiskers catfish Mystus gulio is a commercially important food fish in Asian countries. But natural population is decreasing due to over-exploitation and various ecological changes in its natural habitats. This paper suggests the steps for the conservation of the remnant isolated population of M. gulio in Asian countries.Som dugih brkova, Mystus gulio, je komercijalno važna riba u azijskim zemljama. Ipak, opadaju prirodne populacije zbog pretjeranog iskorištavanja i raznih ekoloških promjena u njihovim prirodnim staništima. U radu se predlažu koraci za očuvanje ostatka izolirane populacije M. gulio u azijskim zemljama

Meta-Data Analysis to Explore the Hub of the Hub-Genes That Influence SARS-CoV-2 Infections Highlighting Their Pathogenetic Processes and Drugs Repurposing

The pandemic of SARS-CoV-2 infections is a severe threat to human life and the world economic condition. Although vaccination has reduced the outspread, but still the situation is not under control because of the instability of RNA sequence patterns of SARS-CoV-2, which requires effective drugs. Several studies have suggested that the SARS-CoV-2 infection causing hub differentially expressed genes (Hub-DEGs). However, we observed that there was not any common hub gene (Hub-DEGs) in our analyses. Therefore, it may be difficult to take a common treatment plan against SARS-CoV-2 infections globally. The goal of this study was to examine if more representative Hub-DEGs from published studies by means of hub of Hub-DEGs (hHub-DEGs) and associated potential candidate drugs. In this study, we reviewed 41 articles on transcriptomic data analysis of SARS-CoV-2 and found 370 unique hub genes or studied genes in total. Then, we selected 14 more representative Hub-DEGs (AKT1, APP, CXCL8, EGFR, IL6, INS, JUN, MAPK1, STAT3, TNF, TP53, UBA52, UBC, VEGFA) as hHub-DEGs by their protein-protein interaction analysis. Their associated biological functional processes, transcriptional, and post-transcriptional regulatory factors. Then we detected hHub-DEGs guided top-ranked nine candidate drug agents (Digoxin, Avermectin, Simeprevir, Nelfinavir Mesylate, Proscillaridin, Linifanib, Withaferin, Amuvatinib, Atazanavir) by molecular docking and cross-validation for treatment of SARS-CoV-2 infections. Therefore, the findings of this study could be useful in formulating a common treatment plan against SARS-CoV-2 infections globally
